 Replying to [comment:2 SergeyBiryukov]:
 > That's the exact purpose of canonical redirects, I don't see a bug here.

 I was wondering about this myself - is it really the intention of
 `redirect_canonical` to redirect from ''any'' domain to the main domain?
 Because a comment in the implementation seems to contradict this:

 https://core.trac.wordpress.org/browser/tags/4.9.8/src/wp-
 includes/canonical.php#L460

 The comment says: `Only redirect no-www <=> yes-www`.  Then the next few
 lines of code seem to be attempting to redirect only if the domains differ
 in having a `www.` prefix.  (But the code doesn't actually work because
 the logic is flawed.)
